The only way I see to make these tests pass is to change the inputCharacters regex to this:

inputCharacters = /(\\)?([0-9]{1,2}\uC6D4|[0-9]+|([a-zA-Z\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+|([\+\-]\d\d:?\d\d))/gi,

@timrwood, It sort of feels like a hack. What do you think?

This is fixed with the new parser. Thanks Rocky for the tests!
